Hi and thanks for the query,
Looks like you have ear as well as throat infection
You can take an over the counter pain killer for the ear ache
and the sore throat
You can also use decongestant nose drops like otrivin
Otrivin will unclog the tube that connects your nose to the ear, thus improving ventilation of the ear which inturn helps to control the ear infection
For using otrivin properly please read the instructions on the crimp.
Instill drops 3 times aday for 5 days.
You may also require an antibiotic, please consult a doctor for the prescription.
Do warm salt water gargling 4 times a day, avoid cold foods and air conditioning.
